Sažetak
The development of clear coatings with minimal use of harmful chemical to extend the lifetime of wood and maintain its natural look has become very important. However, the clear coatings transmit harmful solar radiation, which causes degradation of wood surface. To increase the coating and wood durability and retain transparency of coating, nanosized inorganic UV absorbers are increasingly used. In this research the samples of unmodified and thermally modified ash wood (Fraxinus excelsior L.) finished with nanoparticles-modified waterborne stain were studied. The samples were coated with commercial clear waterborne stain in which the CeO2 nanoparticles were added in three concentrations (1, 2 and 3%). Coated and uncoated wood samples were exposed for six weeks to UV-light and high moisture in QUV tester equipped with UVA-340 fluorescent lamps. During artificial weathering change in colour and gloss was measured and after artificial weathering the change in water permeability was evaluated. The results of colour change (ΔE*) of unmodified and thermally modified ash wood samples showed that CeO2 nanoparticles had a greater impact on colour stability of thermally modified wood than on unmodified wood after artificial weathering.
